I’ve been messing around with video in the beta and wanted to share what functionality I’ve figured out. I want to know what stuff you guys have figured out too.

Warping > It works. Mutate your audio and the video follows along. Fun stuff. When you first drop in a clip in the arranger, it appears unwarped. What’s interesting is that you can speed up or slow down the BPM, or tap in another tempo, and the audio from the video is not altered. It’s kinda wild to see the playhead suddenly zipping along with the audio not changing. Then, if you click the warp button in the clip view, you can now mess with the BPM and the video will follow along. A new slave button appears under the warp button. This is when all of time and space gets fucked with. Say you click the warp button and slow the video down to 60 PBM. If you click the Slave button it turns into the Master button. You are now in ‘Master’ mode, and the BPM is locked at 60. If you click the Master button it turns into Slave again, and as a slave you are free (irony intended) to change the BPM again if you wish.

Full Screen Mode > As easy as double clicking on the video screen. Double click and boom, the video image takes up your entire monitor. Want to quickly get out? Just double click again, you’re back home.

Reverse Button > It will reverse the audio but it makes the video functionality cease. Kind of a bummer. I’d like to see the video image reverse as well. It can inspiring + other worldly to simply watch normal things happen in reverse. This other-worldliness would be right at home in Live.

Multiple Video Clips > You can load multiple video clips but you’re allowed only one video screen. The clip that is at the bottom of the tracks in the arrangement screen gets the right to be viewed in the video screen. So, if a clip of a monkey eating a banana is in track one and a video of a hippy on a unicycle is on track two, the hippy will be on the video screen. If you want to watch the monkey you have to drag that clip from track one and drop it in track three, which requires a redraw of the track. So on a Mac you get the spinning beach ball for a few seconds and the image on the video screen will freeze + along with the GUI, but the audio keeps playing without a burp.

Session View > If you launch video clips in session view you do not have video screen capability. For now it is in arrangement only. If you launch a video clip in arrangement view and then tab over to session view, the video screen will remain and keep playing. There must be a reason why it was decided to only have video in arrangement. But I think it would be cool to have video launchable in session. That way a DJ can become a VJ pretty easily. If you have video clips associated with the cells of clips you are launching in session view in a DJ set, Live’s new video screen could be used as simplified video show for the people shaking their bootys on the dance floor.

What else so far? Sampler is a monster! The loop-modulation granular tricks are almost worth the price of admission, and the LFO/mod routing reminds me of the K2000 series – not quite as deep, but almost as flexible,

Racks are incredible – like we had suspected, set up multiple effect/instrument chains and set them up in specific “select zones” this will let you switch in between chains OR fade in between them. This will be incredible during live sets.

As far as controller support, the SL seems to be working great with it so far (minus quirky modwheel assignments). The right hand fader side seems to act a bit differently than in 5.2 – Where I can only ever get control over send 1 in 5.2, it wants to control send 2 in 6. I’m still on the learning curve with the controller tho.

Let’s see – what else? Pulling in tracks from other session files is much faster now. It’s buggy, but not too buggy. Definately some small touches with the interface (value boxes now have “slider” interface, turning from grey to yellow). So far, so good though!
